Communication Systems
Objectives
• To provide an understanding of the practical
communication systems such as AM and FM radio
and digital modem.
• To introduce the mathematical concepts such as
Fourier transform and random process and apply
them to communication systems.
• To familiarize with various communication systems
such as amplitude modulation (AM) and frequency
modulation (FM) and compare the performance
quality.

Course Outline
The course material will cover the first chapters of Haykin in the
approximate order presented in the text. It is expected that the
material will cover at least Ch. 2,3, 4,7,8 and 9. This material
will include:
• Review of Fourier theory
• Amplitude modulation (AM) systems
• Frequency modulation (FM) and phase modulation (PM)
systems
• Pulse (digital) modulation systems
4
Course Outline
• Review of random processes and noise, and modeling of noise
in communications systems.
• AM, FM and PM in the presence of noise.
5
Labs
There will be approximately 4 labs throughout the
course. The labs will consist of a combination of
computer and hardware experiments. The outline for
the labs is as follows:
• Practical application of Fourier transforms
• Double sideband suppressed carrier modulation
• Random processes and noise.
• AM-FM radio
6
Lab Timeline
• Fourier theory – starts from the third week of Jan’08
and runs for three weeks. The output of a function
generator is passed through a filter. The output of the
filter is analyzed using oscilloscope and spectrum
analyzer. First you will make a computer simulation
using Matlab and later validate it experimentally.
• DSB-SC modulation and demodulation: runs from
the second week of Feb’08 for three weeks. You will
be doing the experiment of modulating a 64 KHz
carrier with a 4 KHz sinusoidal message.
7
Lab Timeline
• Random processes – starts from the second week of
Mar’08. Only numerical experiment using matlab.
Evaluate the autocorrelation and power spectral
density of the output of a filter driven by a white
noise.
• AM-FM radio : You will assemble a radio kit. The
report is due in the first week of April.
